Consent-first capture
Clinicians read a standard consent script and record how consent was given: verbal, written or standing. Nothing is recorded, and no transcript is accepted, until consent is logged.
Ambient clinical documentation
Notes built only from what was said.
Medicaal listens to the consultation, extracts the clinical facts and drafts a structured note in which every sentence traces back to the words that were spoken. Unsupported doses can't be signed. And with smart glasses, clinicians can query the patient's record hands-free.

The scribe
Documentation you can trust, by design
Trust is earned in the details: consent before capture, resilience when the network drops, and a note that tells you when it found very little.
Resilient to network drops
Audio is also kept on the device. Anything live transcription misses during an outage is recovered from that audio before the note is drafted.
Only what was said
Every fact must be found, word for word, in the transcript. Anything that can't be found is discarded, and sections are never padded to look complete.
Evidence, not inference
Who said each fact, and when, is taken from the transcript itself. It is never guessed by a language model.
Honest about gaps
When a section has nothing behind it, the review screen says so, and the exported PDF records it too.
8 facts found; 2 sections are template text, not the consult.
Every edit re-verified
Clinicians can rewrite any section. Changes are checked against the consultation, and an unsupported dose, drug or allergy blocks signing until it's corrected.

Evaluation data
Tested with Genkidata
Vital signs and lab values in our evaluation consultations come from Genkidata, an open, synthetic openEHR dataset published by the Berlin Institute of Health (BIH) under the Apache-2.0 licence. No real patient data is used. Medicaal is not affiliated with BIH.
How it works
One assistant, from consent to signature
Start with the patient's agreement
- Today's list shows every consultation and its status, from consent needed to signed.
- A standard consent script appears on screen, ready to read aloud.
- Clinicians record how consent was given before the microphone opens.
Consent
Sample patient · follow-up
Read aloudI record my consultations so my notes are accurate. The recording is deleted once the note is signed. Is that all right with you?
How was it given?
Verbal Written Standing Start recordingFocus on the patient, not the screen
- Live transcription separates clinician and patient.
- Pause and resume freely. It stays one consultation and one transcript.
- If the network drops, recording continues and the audio is transcribed afterwards.

Review, sign and export
- Clinical facts are extracted on your own server, one category at a time.
- The note is assembled into seven sections: chief complaint, history, examination, investigations, assessment, plan and follow-up.
- Edit any section, sign, and export a PDF. Changes after signing create a new version that must be signed again.
History
Not discussed.
Investigations
Investigation: oxygen partial pressure, 44, mmHg. Investigation: carbon dioxide pressure, 67, mmHg. Investigation: pH, 7.4. Investigation: antibody titre, 240, IU/mL.

Smart glasses
The patient's record, hands-free
On ward rounds and at the bedside, a clinician's hands are often busy or gloved. With AurViz smart glasses and a phone in the pocket, they ask about the patient and hear the answer from the record, with its source.
Scan the wristband
The glasses camera reads the QR code on the patient's wristband.
Confirm it's you
Fingerprint, face or PIN, through the phone's secure system prompt. Without a screen lock, no record opens.
Ask naturally
Speech is recognised on the device, and follow-ups like “and before that?” keep the thread.
Hear the answer
Spoken through the glasses and shown on the phone, with the source document and date.
what's the hb
Hemoglobin 11.2 grams per decilitre, flagged low. Lab report, 14 September.
Read from the recordand before that
Previous hemoglobin 11.6 grams per decilitre. Lab report, 1 September.
Read from the recordshould I stop the apixaban
I can't advise on that. I can read this patient's allergies, medications, labs and reports.
Declined on the device. Never sent.Checked before it's spoken
In field testing, the assistant's language model added a time that the patient's record didn't contain. The answer was stopped before it reached the clinician, and the record was read out instead. Every model answer is checked against the record, line by line, before it is spoken.
Deployment
Runs on your infrastructure
Medicaal runs on your own servers. Records, notes and signatures stay inside your network.
External service
Cloud speech recognition
Converts consultation audio into text and separates the speakers. The only step that leaves your network.

Medicaal for Android
Captures the consultation, keeps a local copy of the audio for recovery, and presents the note for review and signature.

Your servers
Medicaal server
Extracts clinical facts, assembles and verifies the note, records signatures, exports PDFs and keeps the audit trail.
The smart-glasses assistant works without an internet connection: speech is recognised on the device, and questions go only to your Medicaal server.

Security and safety
Safeguards that don't depend on the model
Every AI model can be wrong. Medicaal's safeguards decide what reaches a signature or a clinician's ear.
Server-side signing control
The device only predicts; the server enforces. A note can't be signed while any unverified sentence carries a number, a drug or an allergy.
No clinical advice
Requests for advice are declined on the device before any network call, including those phrased as commands.
Biometric access
Records open only after the device's fingerprint, face or PIN check, and locking clears them from the device.
No sensitive logging
Logs record event types and sizes only, never a transcript, a question or an answer.
Append-only audit trail
Creation, consent, transcript, viewing, signing and export are each recorded with user and time, and no clinical content.
Models never exposed
AI models are bound to the server itself and are never reachable on the network. Devices talk to one Medicaal server at one pinned address.
Questions
FAQs
Is Medicaal cleared for clinical use?
Not yet. Medicaal is in pilot and is not a medical device. It has been tested end to end on real devices with demonstration data, and we're looking for clinical partners for the next stage of evaluation.
How accurate are the notes?
Every fact in a Medicaal note is traced to the words that were spoken, and unsupported doses, drugs and allergies can't be signed. Extraction is still being refined in pilot, so every note is reviewed by the clinician before it is signed.
What data has Medicaal been tested on?
Synthetic and demonstration data only, never real patients. Vital signs and lab values in our evaluation consultations come from Genkidata, an open, synthetic openEHR dataset published by the Berlin Institute of Health. Smart-glasses field testing used demonstration patient records.
Where does patient data go?
Consultation audio is sent to a cloud speech-recognition service for transcription. Everything after that stays on your Medicaal server: facts, notes, verification, signatures, PDFs and the audit trail.
The smart-glasses assistant sends questions only to your server.
Does Medicaal suggest diagnoses or treatments?
No. Medicaal documents what was said and adds nothing. The smart-glasses assistant declines requests for advice on the device, and they are never sent.
Can clinicians edit the note?
Yes, every section. Edits are re-verified against the consultation. An unsupported number, drug or allergy blocks signing until it's corrected, and other unsupported text must be explicitly accepted. Editing a signed note creates a new version that must be signed again.
What happens if the network drops mid-consultation?
Recording continues. Audio is kept on the device, and any missed stretch is transcribed from it before the note is drafted. Anything that can't be recovered is flagged on the review screen.
What hardware do we need?
An Android phone (Android 8 or later, or Android 13 or later for the smart-glasses voice assistant), a server to host Medicaal on your premises, and AurViz smart glasses for hands-free record access.
Does it integrate with our EHR?
Signed notes export as PDF today. Talk to us about connecting Medicaal to your EHR.
